Value Collection 34890 Pull Out Dowel Pin 1/4x2 in Grade 8

Product Description

The VALUE COLLECTION 34890 is a standard pull out dowel pin designed for precision alignment and locating applications in industrial and mechanical assemblies. Machined from Grade 8 alloy steel, it measures 1/4 inch in diameter and 2 inches in overall length, with a diameter tolerance of 0.0002 inches for tight, repeatable fits. The pin features one beveled end and one rounded end, conforming to ASME B18.8.2 standards. Rockwell hardness falls in the C 50-58 range, providing the strength and wear resistance required in demanding service environments. Machinists, millwrights, and maintenance technicians typically install this type of fastener.

This dowel pin is suited for use in jigs, fixtures, dies, and machine components where accurate part-to-part alignment is critical. The pull out design allows for controlled removal without damaging the mating bore, making it practical for assemblies that require periodic disassembly or tooling changeovers. It is appropriate for both light and heavy industrial applications where dimensional consistency and hardness are required by the assembly specification.

Compatibility

Designed as an OEM-style replacement or standard fitment for precision alignment applications requiring a 1/4 inch diameter pull out dowel pin conforming to ASME B18.8.2.

Installation Notes

Dowel pin installation and removal should be performed by qualified machinists or maintenance technicians familiar with precision fastener tolerances. Ensure mating bores are clean, deburred, and dimensionally verified before pressing or driving the pin into position. Use appropriate pressing or extraction tools rated for the pin diameter to avoid damaging the bore or the pin. Follow applicable machinery safety lockout and tagout procedures before servicing any assembly containing dowel pins.
